Toolex Reamer – Straight Shank – Spiral Flute – HSS-E, 12.30 mm is a precision finishing tool built for machinists who need accurate hole enlargement and smooth bore finishes. Designed for reliability in metalworking environments, it delivers consistent, tight hole tolerances across a range of materials.

• Diameter: 12.30 mm
• Material: HSS-E (high-speed steel with cobalt) for enhanced heat resistance and wear life
• Flute Design: Spiral flute for efficient chip evacuation and reduced chip buildup
• Shank Type: Straight shank for broad compatibility with a variety of tool holding systems
• Function: Precision hole enlargement and finishing to achieve accurate diameters and smooth bore quality
• Performance: Consistent cutting action and concentricity, ideal for multiple passes and difficult materials

This reamer excels in finishing operations where achieving a precise diameter is critical. The cobalt-infused HSS-E construction provides durability under heat, extending tool life even during demanding jobs. The spiral flute design not only aids chip evacuation but also contributes to a cleaner hole with less friction, helping maintain tight tolerances and a polished surface finish. Thanks to the straight shank, it integrates smoothly with standard collets, chucks, and holders in diverse machining setups, making it a versatile choice for workshops that demand reliable, repeatable results.
